Product: Pneumatic thread end ball valve

Introduction

Pneumatic threaded ball valve adopts automatic CNC numerical control processing with smooth inner cavity and excellent sealing performance. It is widely used in industrial control occasions such as food, environmental protection, petroleum, papermaking, chemical electric power and other industries.

Working principle

It is composed of a rotary pneumatic actuator and a ball valve, which is suitable for cut-off and adjustment. It relies on air supply to realize operation of 0℃-90 ℃ with limit switch to prevent misoperation.

Features:

1. The cylinder is made of aluminum alloy material, and rack and pinion configuration has a large output torque ;

2. It adopt high mouting platform, which can be directly connected with the cylinder, avoiding the shortcomings of cylinder accuracy deviation caused by loose bracket ;

3. It is easy to operate and quick to open and close. It only needs to rotate 90° from fully open to fully closed to facilitate remote control;

4. The fluid resistance is small, and the resistance coefficient is equal to that of the pipe section of the same length ;

5. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and when the medium passes, it will not cause corrosion of the valve sealing surface;
